Patented Mar. 14, 1939 UNITED STATES ATENT OFFICE Application April 29,

1 Claim.

The invention relates more particularly to a device for the prevention of the collapse of masonry veneer over Wood frame construction or any type of construction to which the tie may be attached.

An object of the invention is to provide a continuous tie constructed of wire of any size made in lengths with portions returning back to a point of attachment with laps only at the point of attachment.

A feature of the invention is that the tie may be placed in advance of the masonry at required levels and will remain flat against the-building out of the way until the masonry is built upto 5 the required height to receive it.

Another object of the invention is that the wire is so bent in the form of a shear and tension reinforcement bar between points of support giving a beam action.

Simplicity with maximum strength and cheapness of construction are other objects.

Other objects, advantages and features of the invention may appear from the accompanying drawing, the subjoined detailed description and. the appended claim.

The accompanying drawing illustrates the invention.

Figure l is a fragmental perspective view partly in section of the masonry tie assembly showing as applied to a masonry veneer construction over a wood frame construction.

Fig. 2 is a plan detail view of the tie.

Fig. 3 is a plan detail view of another type of tie.

Referring to Fig. 1 only such portion of a type of building construction that illustrates the location and method of applying the tie of my invention is shown. The studding I is shown having sheathing 2 fixed thereto and showing the tie 3 fixed to the sheathing 2 by the staples 4.

In this construction the ties 3 may be placed in advance of the masonry 5 and will remain at required levels against the sheathing as at 6 out of the way until the masonry is built up to the required levels to receive it as shown at 1.

1935, Serial No. 18,849

The tie .1 is so constructed and arranged to form a continuous shear bar 8 between points of support and giving a beam action and may be made of wire of any size and length with ends returning back to a point of attachment with laps 9 at the point of attachment.

The distance between points of attachment may be made uniform or variable depending upon the construction to which it is to be attached A return hook It is provided at each end of the tie 3 so that it extends beyond the attaching member forming an anchor that prevents the tie from slipping when set in the masonry.

Fig. 3 shows another form of tie having one member H straight and the other member having'the form as shown at l2 which may be fixed together to form a tie at the place of attachment not shown.

I claim:

A continuous masonry tie for the continuous reinforcement and attachment of brick veneer to wood frame construction comprising a plurality of lapped Wire units; each unit being provided with a return hook at its ends;- each unit bent in a series of three sided angular loops; the adjoining sides of adjoining loops converging to short longitudinal straight portions at the points of attachment to wood frame construction that the distance between the outermost bends of ad joining loops is less than the length of one brick, to permit a superimposed and underlying brick to span the gap between said loops; and that the short longitudinal portions at points of attachment to wood frame are less than one half of the distance between the outermost bends of adjoining loops; that at each end of each unit the short longitudinal portion is continued and bent back horizontally to lie in the mortar joint parallel to the side of the adjoining loop, preserving longitudinal continuity from unit to unit, because of the hooked ends being lapped and attached to the wood frame.
